DESCRIPTION

       The QDockArea class manages and lays out QDockWindows.

       A QDockArea is a container which manages a list of QDockWindows which it lays out within its area. In cooperation with the QDockWindows it
       is responsible for the docking and undocking of QDockWindows and moving them inside the dock area. QDockAreas also handle the wrapping of
       QDockWindows to fill the available space as compactly as possible. QDockAreas can contain QToolBars since QToolBar is a QDockWindow
       subclass.

       QMainWindow contains four QDockAreas which you can use for your QToolBars and QDockWindows, so in most situations you do not need to use
       the QDockArea class directly. Although QMainWindow contains support for its own dock areas it isn't convenient for adding new QDockAreas.
       If you need to create your own dock areas we suggest that you create a subclass of QWidget and add your QDockAreas to your subclass.

       Lines. QDockArea uses the concept of lines. A line is a horizontal region which may contain dock windows side-by-side. A dock area may have
       room for more than one line. When dock windows are docked into a dock area they are usually added at the right hand side of the top-most
       line that has room (unless manually placed by the user). When users move dock windows they may leave empty lines or gaps in non-empty
       lines. Dock windows can be lined up to minimize wasted space using the lineUp() function.

       The QDockArea class maintains a position list of all its child dock windows. Dock windows are added to a dock area from position 0 onwards.
       Dock windows are laid out sequentially in position order from left to right, and in the case of multiple lines of dock windows, from top to
       bottom. If a dock window is floated it still retains its position since this is where the window will return if the user double clicks its
       caption. A dock window's position can be determined with hasDockWindow(). The position can be changed with moveDockWindow().

       To dock or undock a dock window use QDockWindow::dock() and QDockWindow::undock() respectively. If you want to control which dock windows
       can dock in a dock area use setAcceptDockWindow(). To see if a dock area contains a particular dock window use hasDockWindow(); to see how
       many dock windows a dock area contains use count().

       The streaming operators can write the positions of the dock windows in the dock area to a QTextStream. The positions can be read back later
       to restore the saved positions.

       Save the positions to a QTextStream:

	   ts << *myDockArea;

       Restore the positions from a QTextStream:

	   ts >> *myDockArea;

   Member Type Documentation
QDockArea::HandlePosition
       A dock window has two kinds of handles, the dock window handle used for dragging the dock window, and the splitter handle used to resize
       the dock window in relation to other dock windows using a splitter. (The splitter handle is only visible for docked windows.)

       This enum specifies where the dock window splitter handle is placed in the dock area.

       QDockArea::Normal - The splitter handles of dock windows are placed at the right or bottom.

       QDockArea::Reverse - The splitter handles of dock windows are placed at the left or top.

MEMBER FUNCTION DOCUMENTATION

QDockArea::QDockArea ( Orientation o, HandlePosition h = Normal, QWidget * parent = 0, const char * name = 0 )
       Constructs a QDockArea with orientation o, HandlePosition h, parent parent and called name.

QDockArea::~QDockArea ()
       Destroys the dock area and all the dock windows docked in the dock area.

       Does not affect any floating dock windows or dock windows in other dock areas, even if they first appeared in this dock area. Floating dock
       windows are effectively top level windows and are not child windows of the dock area. When a floating dock window is docked (dragged into a
       dock area) its parent becomes the dock area.

int QDockArea::count () const
       Returns the number of dock windows in the dock area. See the "count" property for details.

QPtrList<;QDockWindow> QDockArea::dockWindowList () const
       Returns a list of the dock windows in the dock area.

HandlePosition QDockArea::handlePosition () const
       Returns where the dock window splitter handle is placed in the dock area. See the "handlePosition" property for details.

bool QDockArea::hasDockWindow ( QDockWindow * w, int * index = 0 )
       Returns TRUE if the dock area contains the dock window w; otherwise returns FALSE. If index is not 0 it will be set as follows: if the dock
       area contains the dock window *index is set to w's index position; otherwise *index is set to -1.

bool QDockArea::isDockWindowAccepted ( QDockWindow * dw )
       Returns TRUE if dock window dw could be docked into the dock area; otherwise returns FALSE.

       See also setAcceptDockWindow().

bool QDockArea::isEmpty () const
       Returns TRUE if the dock area is empty; otherwise returns FALSE. See the "empty" property for details.

void QDockArea::lineUp ( bool keepNewLines ) [slot]
       Lines up the dock windows in this dock area to minimize wasted space. If keepNewLines is TRUE, only space within lines is cleaned up. If
       keepNewLines is FALSE the number of lines might be changed.

void QDockArea::moveDockWindow ( QDockWindow * w, int index = -1 )
       Moves the QDockWindow w within the dock area. If w is not already docked in this area, w is docked first. If index is -1 or larger than the
       number of docked widgets, w is appended at the end, otherwise it is inserted at the position index.

void QDockArea::moveDockWindow ( QDockWindow * w, const QPoint & p, const QRect & r, bool swap )
       This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

       Moves the dock window w inside the dock area where p is the new position (in global screen coordinates), r is the suggested rectangle of
       the dock window and swap specifies whether or not the orientation of the docked widget needs to be changed.

       This function is used internally by QDockWindow. You shouldn't need to call it yourself.

Orientation QDockArea::orientation () const
       Returns the dock area's orientation. See the "orientation" property for details.

void QDockArea::removeDockWindow ( QDockWindow * w, bool makeFloating, bool swap, bool fixNewLines = TRUE )
       Removes the dock window w from the dock area. If makeFloating is TRUE, w gets floated, and if swap is TRUE, the orientation of w gets
       swapped. If fixNewLines is TRUE (the default) newlines in the area will be fixed.

       You should never need to call this function yourself. Use QDockWindow::dock() and QDockWindow::undock() instead.

void QDockArea::setAcceptDockWindow ( QDockWindow * dw, bool accept )
       If accept is TRUE, dock window dw can be docked in the dock area. If accept is FALSE, dock window dw cannot be docked in the dock area.

       See also isDockWindowAccepted().

   Property Documentation

       Get this property's value with isEmpty().

HandlePosition handlePosition
       This property holds where the dock window splitter handle is placed in the dock area.

       The default position is Normal.

       Get this property's value with handlePosition().

Orientation orientation
       This property holds the dock area's orientation.

       There is no default value; the orientation is specified in the constructor.

       Get this property's value with orientation().

RELATED FUNCTION DOCUMENTATION

QTextStream &; operator<< ( QTextStream & ts, const QDockArea & dockArea )
       Writes the layout of the dock windows in dock area dockArea to the text stream ts.

       See also operator>>().

QTextStream &; operator>> ( QTextStream & ts, QDockArea & dockArea )
       Reads the layout description of the dock windows in dock area dockArea from the text stream ts and restores it. The layout description must
       have been previously written by the operator<<() function.

       See also operator<<().
